Sharpy Knowledge

How should we choose and buy the Beam Sharpy?

200W Beam Light or we can call it 5R Beam Light. The reason we called 5R Beam is because of the lamp model of  Clay Paky Sharpy: Philips MSD Platinum 5R. There are three versions on the market: Philips, Yodn, Osram.

Here I would like to focus on Philips lamp.

Now, every factory says they use the Philips MSD Platinum 5R, but they will really provide you with the Philips UHP Lamp(projector lamp) when they shipped the devices. The price gap between 5R and UHP is highly at 200USD, so you can think about the difference of lifespan and effect. Attached the pictures for some customers who are not clear about the technical things to avoid of being cheated.

Osram Lamp, Originanl and UHP difference:

Nowadays, many different prices on the Beam Sharpy in Chinese market: Three to four hundred dollars, five to six hundred dollars, even there are one thousand dollars price.  All is the same 200W Beam, why is there such a different price gap?

1. Different device mould
Most of the factories use the common device mould for it’s cheap price.
It’s copied from Clay Paky Sharpy, the shape and structure are fixed. As the materials can not be same as Clay Paky, there will be a safety potential hazard and unstable performance. But the private device can be solve this problem for it’s specially designment.

2. Different lens
Glass lens use three glass to one combination with expensive price and effective optic. Fresnel lens is only with one cheap acryl lens, it will be yellowing ,easy to be broken and dirty after being used some time. The price of fresnel is 1.5 to 3USD per pcs, glasses lens is about 80USD per set.

3. Different motor
Due to the heavy 3in1 glass lens, the pan&tilt movement speed is getting more difficult. The 3-phase motor can provide more power than 2-phase and perfect performance in rotating speed and emergency stop. The factories who sell the Beam Sharpy in middle prices are using 2-phase motors because it's cheaper. But XY rotation principle depends on the cooperation of program and motors, it will be out of step and inaccurate positioning if there is even a little deviation. But we have a professional R&D team, we design the PCB mainboard, program and device mould by ourselves.What we use is 2-phase motor, but as we designed the program and PCB independently, our Sharpy's XY rotating can also reach the same effect as the one used by 3-phase motor. Our maximum speed for Pan needs 2.53 seconds, slower 0.08sec than Clay Paky Sharpy. The maximum speed for Tilt is 1.32sec, only slower 0.02sec than Clay Paky Sharpy.

4. Prism zoom effect
The 8-facet prism is standard configuration for Sharpy Beam, but not standardizing for prism zoom effect(Channel 7). Prism zoom effect can make the gobo become big and small with the prism rotating and prism shaking to show a 3D& dreamlike effect.
The reasons of different cost are mainly as above four points.

Now, please see the following pictures:

It’s easy to distinguish through the pictures that our Yodn 200W is best effective for its high uniformity of luminance pattern. Not like Philips UHP, luminance focus on the middle part overly and the edge is pale.
After having compared our devices and another device, there are several differences as follows:

No.1 Optical(Lens,prism,etc)
—We all use the YL optical(Optical OEM of Martin), price is 16USD higher than theirs.

No.2 Belt&wire
--We use the Fulo belts&Wires. All wires are more thick and flexible. 

No.3 Power supply&PCB mainboard&Program
--The power supply we used is MinWei brand. PCB and program are self-designed, also original program available.

No.4 Fan
   --The fan is one of the important parts to assure the lifespan. We use the Sunon&NMB fans, price is 5USD higher. 

No.5 Pan&Tilt rotating
   --The another device is shaking badly when Pan&Tilt is rotating and can not stop exactly.

No.6 Private device mould
   --Our mould is a little bigger, besides there are two more cooling hole to make sure the lifespan and stable performance.

I strongly suggest my all esteemed customers who are planning to buy Sharpy to visit factories:Check the company strength, monthly sales, the products’ internal structure, function etc. Check the price and after service.
Hope this will help you to know a little more about Beam Sharpy.
Thanks for your attention!
